An in-depth look behind the scenes of the responsive relaunch of People Magazine’s mobile site that Josh, Karen, and Ethan were involved in. I love it when people share their process and build stories like this.

I don’t really want a label. I hate labels. I loathe the term “user experience designer”, because I still believe that “user experience” is just a fundamental to what you’re doing, and shouldn’t need stating. There is nothing but user experience design if you’re building products for people.

This looks like a really handy tool for reducing the file size of JPEGs without any perceptible loss of quality (in much the same way that ImageOptim works for PNGs)—available as a Mac app or an installable web service.

This is just wonderful! It combines almost all of my recent obsessions into one unified post: website performance (particularly on mobile) and the locations of undersea cables. The interactive map is the icing on the cake.

Remember when I linked to the story of Twitter’s recent redesign of their mobile site and I said it would be great to see it progressively enhanced up to the desktop version? Well, here’s a case study that does just that.

Leisa nails it. The real stumbling block with trying to change the waterfall-esque nature of agency work (of which Clearleft has certainly been guilty) can be summed up in two words: sign off.

And from a client’s perspective, this emphasis on sign-off is completely understandable.

It takes a special kind of client to take the risk and develop the level of trust and integration required to work the way that Mr Popoff-Walker any many, many other inhabitants of agency world would like to work.

A great behind-the-scenes look at the redesign (and redevelopment) of Twitter’s mobile subdomain silo. Man, I would love to see this progressively enhanced up to the current widescreen view for “desktop” browsers without the need for separate URLs for any class of device.

What makes the web beautiful is precisely that there are multiple browsers and, if you build things correctly, your sites and applications work in them all. They might not necessarily work exactly the same in them all, but they should still be able to work. There is absolutely nothing preventing you from using new features in your web applications, that’s what progressive enhancement is all about.

Kellan explains the tech behind Old Tweets …and also the thinking behind it:

I think our history is what makes us human, and the push to ephemerality and disposability “as a feature” is misguided. And a key piece of our personal histories is becoming “the story we want to remember”, aka what we’ve shared.

Yes, yes, yes! Karen drives home the difference between mobile and local (and there’s more about the myth of the mobile context).

If you’re making an argument for delivering different content to mobile users, or prioritizing content differently based on their context of use, stop for a minute and ask yourself if you mean local content. And if you do mean local content, then say that. Claiming that your travel example extends to cover the “mobile use case” leaves out millions of tasks and users.

Just to belabor this point: people use mobile devices in every location, in every context. Just because you know what type of device someone is using or where she is doesn’t tell you anything about her intention.
